Is there a way to set a header key based on SSL ID value with HAProxy 1.5? We would like to use the SSL ID as the session ID for clients who do not support cookies.
First, to my knowledge, the answer is no.

To be clear, I'm not suggesting that you use ASP.NET. I'm just suggesting that you use the technique. :)
